I found one interesting example here (now we are getting OT...):
http://www.lammertbies.nl/comm/info/GPS-time.html

It uses a Garmin GPS 18x LVC sensor with bare wire attachments. One
wire contains the PPS (pulse per second) output, which generates one
pulse of 100 ms every second and starts within a microsecond of UTC
second transition!

The page also contains instructions on how to make a Linux time server
based on this device.
